Python tinydb - 如何获取特定元素名称？

Question

This is what my structure looks like:

{'MovieName': 'Its-a-Wonderful-Life', 'Description': 'MovieDiscription', 'IMDBID': '0038650'}

I want to print out only the MovieName element.

I'm using this code to get it:

db = TinyDB('Databases/Downloaded_Movies.json')

for item in db:

   print(item.MovieName)

but I'm getting this error:

 AttributeError: 'Document' object has no attribute 'MovieName'

How do I fix the code?

TinyDB expects an indexed table document, not a list. Unless you want to write a custom middleware for your TinyDB, you'll either have to modify your JSON

"1 ": {'MovieName': 'Its-a-Wonderful-Life', 'Description': 'MovieDiscription', 'IMDBID': '0038650'}

or you can try to print the element with indexes as

import json
wjson = db.read()    
wjdata = json.loads(wjson)
print wjdata['1'][0]['Moviename']
